Let's Code MS DOS 0x15: Sine Tables

I got a question in the YouTube comments about the sine tables that we used for a few animations, like the Copper Bars, the Smooth Scrolling etc. In this episode I try to explain why and how to create sine tables. The idea is to speed up computations, since computing the sine or cosine — even with an FPU — takes an awfully long time on early MS DOS machines.

Oh I forgot: I reviewed The Curse of Rabenstein. A new homebrew game for MS DOS and many other platforms!

SwinSID Nano is known to be a fairly poor emulation in terms of being pitch correct; it also bugs out and artifacts a lot more than the others. I believe the SwinSID Ultimate is a lot better but it's not open source either?

The SwinSID Ultimate is out of stock everywhere and it seems it's easier to buy a genuine SID than the Ultimate. Hence it's not a viable option, IMHO. The ARMSID is readily available and at least as good as the Ultimate, while being even cheaper. Not sure if the ArmSID supports paddles (the Ultimate does) but vor the Renovation that's irrelevant anyway.

I didn't know about its availability, sorry. My interest in C64 stuff is limited to watching Adrian Black restore them and Jan Beta (almost) destroy them 😀 AFAIK ArmSID is even better than SwinSID ultimate.

Yeah, tha ArmSID is really nice. And if on a budget, the SwinSID nano is "good enough" to tinker around with the SID on a PC and get started with SID coding. For the C64 I think the nano is probably too crappy.

I figure this will be of interest to some of you. I'm going through a whole bunch of shovelware CD-ROMs on my stream tonight to see if we can find anything interesting. Fun starts at 7 PM PDT (i.e. in ~45 mins.) Come out & join the spelunk!

^^ No worries! Nothing too exciting, a bunch of FLI/FLC animations, some REALLY bad MOD files (and a couple good ones), a VR Studio game I've never seen bfore, a promitional nutrition & fitness guide published by Buick(!), a mech botmatch game written by one person in 1992, and a janky Wolfenstein street fighter mod that I actually "beat". Classic shovelware, in other words. 😀

I have more of these, including some Doom CDs. Gonna try to stream a few times this week at least. Really pushing to get some activity on the channel.

Edit: I have some UTTER madness I got off Itch lined up tonight. Tune in at 7PM PDT if you're into encoder-killing psychedelia. https://twitch.tv/oldskooljay

Streaming some first-person puzzle games again tonight. Heckling & blurting out solutions welcome! Link above ... or below, in my sig. 😀 Come join the fun!

How To Learn SMD Soldering

Watchlisted for viewing upon return as I am currently travelling. This is something I really need to learn myself. Thanks!

@root42 - cool, thanks! I'm also in the "want to learn SMD" camp, although I suspect I need a better iron. I skimmed it already but will give it a proper watch when I have time. 😀

The ATX2AT PC Saver

In 2019 Sam Demeulemeester (he’s actually Belgian, although I say French in the video) did a Kickstarter for the ATX2AT smart adapter. It allows you to safely attach a modern ATX PSU to a retro mainboard with AT connectors. That is your precious 286, 386 or higher will now be safe from overcurrents due to wrongly inserted CPUs, broken expansion cards, failing tantalum capacitors or rogue power supplies. It might not save the world, but it will probably save your valuable retro PC. I already lost two precious mainboards and am glad to have finally received the ATX2AT smart adapter!
